There are high UV emission bulbs and Low UV emission bulbs and they both work off 36 watts which is the amount of electricity needed to power the lamp. Using a weaker light with less UV light output will under-cure Shellac.
Then there is the placement of the bulbs in the lamp so that the hand or foot will be in the centre where the highest UV output is found.
Then there is the distance of the fingers from the light which has to be considered.
Then there is the convenience and the placement of the bulbs to ensure a 5- finger (whole hand) cure of all nails with the thumbs being at a different angle.
To ensure all these things CND have produced the perfect lamp, placement, UV output, distance etc to ensure a complete cure of Shellac.
Then there is this which your research should have found first.

I did take all that in to account with my research. The question is and remains is how does the UV output of the CND lamp bulbs differ significantly then other similiar 36 watt UV lamps with 9 watt UV bulbs. If anyone can provide an answer to that I would be very interested. Thanks.
